UNITED STATES PATENT QFFIOE JAMES H. LEWIS, OF DETROIT, MICHIGAN,ASSIGNOR OF ONE-HALF HIS RIGHT TO GEORGE H. STELLWAGEN, OF SAME PLACE.

IMPROVEMENT IN BENCH-TOOLS.

Specification forming part of Letters Patent No. 2| 1,5 15, datedJanuary 21, 1879; application filed September 18, 1878.

To all whom it may concern:

Be it known that I, JAMES H. LEWIS, of Detroit, in the county of Wayneand State of Michigan, have invented an Improvement in Bench-Tools, ofwhich the following is a specification:

The nature of my invention relates to certain new and usefulimprovements in hand or bench tools of the spokeshave class for workingcurved moldings, having for its object to so construct the same as toenable the operator to work with the grain of the timber when itreverses in direction, thus avoiding the expense of a second tool of thesame configuration.

The invention consists in providing the segment stock or head with twothroats and cutters, inclined toward each other, as is more fullyhereinafter set forth.

In thedrawin gs, Figure lis aperspecti ve view of my device. Fig. 2 is across-section of the same; and Fig. 3 is a vertical longitudinalsection, showing the relative position of the centers.

In the accompanying drawings, which form a part of this specification, Arepresents a metal stock or head, being a segment whose face has thecross-section of the molding that is to be produced. a are throats,inclined toward each other, as shown, and in which are secured thecutter-bits B by means of clampplates B and screws 1), or in any otherconvenient manner. These bits have a contour at the cutting-edge adaptedto produce a molding of the desired cross-section, but are designed tocut in opposite directions, so thatin working a curved molding eitherbit may be used to cut with the grain when it reverses its direction, asit necessarily does, thus avoiding the necessity of having a pair ofsuch tools for working each pattern of molding, the one having a reversecut from that of the other.

The handles aremade detachable, as shown; but itis evident that thestock may be provided with permanent or stationary handles, if desired.

What I claim as my invention is- The bench-tool described, consisting ofthe segmental head A, having the throats'a a and the cutters 13, securedin opposite directions in said head by the adj ustahle plates B andscrew 12, substantially as and for the purpose set forth.
